目前，我国开发的新药产品绝大部分是仿制国外已经上市的产品，自己发明的新药很少，随着我国专利法的修订和药品行政保护条例的实施，仿制国外的产品将越来越困难。我国对药品的生产技术给予专利保护已有１２年的时间，１９９３年以前的保护仅限于对药品的制造方法的保护... At present, the vast majority of new drug products developed in China are imitations of products that are already listed overseas. Few new drugs are invented by themselves. With the revision of the Patent Law of China and the implementation of the administrative regulations on drug administration, it will become more and more difficult to imitate foreign products. China has granted patent protection for the production technology of pharmaceutical products for 12 years, and the protection before 1993 was limited to the protection of the manufacturing methods of medicines.
